This looked like a very good value on the website but now, I regret it. The install was not hard however they did fail to supply the bolt needed to mount the driver side hanger (which i had to go buy after the truck was on the lift). It looks cool but isn't much louder than stock exhaust on the outside but on the inside, its terrible. I have never heard such a terrible drone in my life. At 1700 rpm it feels like its boring a hole though your skull. I would not buy this again.
You can feel the added hp
Had a little trouble getting it to seal to the factory pipe , but after that the rest of the installation went well. The sound is just right, not too loud with a little bit of drone inside the cab and only slightly louder than the factory system at cruising speed. I really like the way the dual tips exit side by side behind right rear tire.
